Abstract: Folder apparatus for holding and positioning a plurality of transparencies for projection by an overhead projector includes a base panel with two wing panels extending outwardly and in opposite directions from and secured to the base element. The transparencies are disposed against one wing panel and are movable from the position against the one panel to a position on the base panel for projection, and are movable from the projection position on the base panel to a storage position against the other panel. Transparencies include a base element with extensions through which extend holes or apertures. The holes or apertures receive guide rods which are secured to the base panel. The transparencies move on the guide rods. A gradual reveal frame for gradually revealing material on the transparency being projected is also disclosed.
